摘要
本文给出广义二重积分(integral from n=a to ∞)(integral from n=b to ∞(f(x,y)dxdy)) 的优化中心数值积分法,它在选代计算过程中免去了重复计算,加速达到近似值精度,并给出了误差估计式。
This paper will give the optimality center algorithm method of double integ-ral integral from n=a to ∞ integral from n=b to ∞ f (x, y) dxdy and the absolute error. In the course of substitutionthis method can reduce the repetitions of calculating function values and accele-rate the accuarcy of the approximate value.
